AS3Sender Class
Properties Methods Events Config Settings Errors
The AS3Sender class implements an AS3 / EDI-INT client.
Syntax
ipworksedi.as3sender()
Remarks
The AS3Sender component may be used to send EDI or other messages over FTP/S, using the AS3 protocol. It may also be used to verify Message Disposition Notifications (MDNs) returned by the server.
A typical AS3 transaction is as follows:
(1) The sender sends an EDI document to the receiver using FTP. The document may be signed, encrypted, and/or compressed, and a signed or unsigned receipt may be requested.
(2) The receiver decompresses and decrypts the message and verifies the signature.
(3) The receiver sends a signed receipt back to the client. The signature is over the hash of an MDN, which contains a hash of the received message.
When sending an EDI message, the client should specify, at a minimum, AS3From and AS3To, EDIDataData, and EDIDataEDIType. You will also need to specify User, Password, and RemoteHost to Logon to the FTP server. After doing this you may send the data by calling Send.
To secure the EDI transmission, the message may be signed and/or encrypted by setting the appropriate certificates. By default, the class will apply message security if the appropriate certificates are specified. To sign the data set SigningCert. To encrypt, set RecipientCerts.
TLS/SSL may be enabled by setting the SSLStartMode property. In case your trading partner is using a self-signed certificate it will be necessary to set SSLAcceptServerCert or trap the SSLServerAuthentication event to accept the certificate.
The message may also be compressed by setting CompressionFormat.
To request a receipt, or Message Disposition Notification (MDN), simply set the MDNTo property. The MDN will be returned to the FTP URL specified. The MDNOptions property may be used to customize the request. By default, the class will request a signed MDN over an SHA1 hash.
Validating AS3 MDNs
AS3 MDNs will be returned asynchronously over a separate connection. You may verify MDNs by invoking ReadReceipt. This will read the receipt from the FTP server (or from the MDNReceipt property). It will determine the MessageId of the original message and determine the originator and recipient of the MDN.
You should then look up your trading partner's certificates as well as the OriginalContentMIC (which you must store externally to verify signed receipts), and invoke VerifyReceipt.

Syntax
getAttachments(): EDIAttachmentList; setAttachments(attachments: EDIAttachmentList): void;
Default Value
Remarks
When a call to Send is made, the class will attach the files referenced by each EDIAttachment in this collection to the EDIData.
This property is not available at design time.
AS3Sender.CompressionFormat Property
The compression format (if any) to use.
Syntax
getCompressionFormat(): As3senderCompressionFormats; setCompressionFormat(compressionFormat: As3senderCompressionFormats): void;
enum As3senderCompressionFormats { cfNone, cfZLIB }
Default Value
0
Remarks
By default, outgoing data will not be compressed. Setting this property will instruct the class to compress the outgoing data using the indicated format.
Compression is highly recommended for large messages, as it will reduce network bandwidth and processing time required.
The compression algorithm used is Zlib, as required by RFC 3274 and defined in RFCs 1950 and 1951.
AS3Sender.Connected Property
This shows whether the class is connected.
Syntax
isConnected(): boolean;
Default Value
FALSE
Remarks
This property is used to determine whether or not the class is connected to the remote host.
Note: It is recommended to use the Connect or Disconnect method instead of setting this property.
This property is not available at design time.
AS3Sender.EDIData Property
The EDI or other data to be sent.
Syntax
getEDIData(): EDIData; setEDIData(EDIData: EDIData): void;
Default Value
Remarks
The EDI message to send.
This property is not available at design time.
AS3Sender.EncryptionAlgorithm Property
The algorithm used to encrypt the EDI data.
Syntax
getEncryptionAlgorithm(): string; setEncryptionAlgorithm(encryptionAlgorithm: string): void;
Default Value
"3DES"
Remarks
If RecipientCerts contains a valid certificate, the data will be encrypted using this certificate and the algorithm specified in EncryptionAlgorithm. If EncryptionAlgorithm is set to the empty string, the data will not be encrypted.
The class supports "3DES", or industry-standard 168-bit Triple-DES encryption.
The class supports "AES" encryption with a default keysize of 128 bits. You may also set "AESCBC192" or "AESCBC256" for 192- and 256-bit keysizes.
Possible values are:
- 3DES (default)
- DES
- AESCBC128
- AESCBC192
- AESCBC256
- AESGCM128
- AESGCM192
- AESGCM256
AS3Sender.Firewall Property
A set of properties related to firewall access.
Syntax
getFirewall(): Firewall; setFirewall(firewall: Firewall): void;
Default Value
Remarks
This is a Firewall type property which contains fields describing the firewall through which the class will attempt to connect.
AS3Sender.FTPLastReply Property
The last reply from the FTP server.
Syntax
getFTPLastReply(): string;
Default Value
""
Remarks
The last reply from the FTP server.
This property is read-only.
AS3Sender.LocalHost Property
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
getLocalHost(): string; setLocalHost(localHost: string): void;
Default Value
""
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.
AS3Sender.LogDirectory Property
The path to a directory for logging.
Syntax
getLogDirectory(): string; setLogDirectory(logDirectory: string): void;
Default Value
""
Remarks
Setting LogDirectory will instruct the component to log the details of each transmission to unique files in the specified directory. For each request processed, the class will log the original EDI data, the complete text of the outgoing request and the incoming response.
The class will write a file for each transmission, with extension ".log". In case of error an additional file will be written with extension ".err", and the error will be reported in both files. Raw AS3 messages created or downloaded by the class will be written with extension ".as3", and MDNs created or downloaded will be written with extension ".as3-mdn".
The filenames will be chosen automatically by the class. Each filename will be the system time, in the format YYYY-MM-DD-HH-MM-SS-MMMM, with extensions "-2", "-3", used in case files of those names already exist. After each transaction is processed LogFile will contain the name of the files just written, minus the extension ".log" or ".err".
If logs cannot be written an exception will be thrown.
AS3Sender.LogFile Property
The log file written.
Syntax
getLogFile(): string;
Default Value
""
Remarks
In case LogDirectory is specified two log files will be written in the specified directory and LogFile will contain the path.
LogFile will in fact refer to several files with appropriate extensions. A diagnostic log will be written with filename LogFile + ".log", and any EDI data read will be written with filename LogFile + ".dat". Raw AS3 messages and MDNs will also be written with extensions ".as3" and ".as3-mdn".
This property is read-only.
AS3Sender.MDNOptions Property
Used to indicate the options requested for the MDN receipt.
Syntax
getMDNOptions(): string; setMDNOptions(MDNOptions: string): void;
Default Value
"signed-receipt-protocol=optional, pkcs7-signature; signed-receipt-micalg=optional, sha-256"
Remarks
By default, the class will request that the MDN be signed with a PKCS#7 signature over a SHA-256 hash, which is the industry standard.
Set MDNOptions to an empty string to request an unsigned receipt.
This property will automatically be updated when SignatureAlgorithm is set. Normally you will not need to set this property, however you can set a value here to override the automatically generated value.
The string format is that of the Disposition-Notification-Options HTTP header, as specified in RFC 3335. As a form of shorthand, you may set this property to "sha1", "sha-256", or "md5" to request the indicated hash algorithm.
AS3Sender.MDNReceipt Property
The MDN receipt returned from the server.
Syntax
getMDNReceipt(): MDNReceipt; setMDNReceipt(MDNReceipt: MDNReceipt): void;
Default Value
Remarks
This property will contain an instance of MDNReceipt with the complete MDN receipt returned from the AS2 receiver. The receipt will be a signed or unsigned multipart/report in MIME format. For synchronous MDN requests, this property is populated automatically after the call to Post. If an asynchronous MDN is sent over HTTP, it may be read from the HTTP context by calling ReadAsyncReceipt, or it may be set manually.
When MDNReceipt is set to a valid MDN receipt, the originator of the receipt will be stored in AS2To, the intended recipient (presumably your system) will be stored in AS2From, and the original message ID will be stored in MessageId.
If you are processing a MDN receipt asynchronously, you can use the values to look up the original message and validate the receipt. Set the OriginalContentMIC, MDNOptions, and ReceiptSignerCert to the values originally computed when the message was sent (if you are requesting async MDNs you must save this information externally.). You can then validate the asynchronous receipt by invoking VerifyReceipt.
Alternatively, AsyncMDNInfoDir may be set in place of OriginalContentMIC, MessageId, and MDNOptions (provided it was set to the same value when the message was sent). If AsyncMDNInfoDir was specified when the message was sent, the class would have saved OriginalContentMIC and MDNOptions to a file identified by the MessageId for the transmission. These properties are read from the file matching the MessageId in the MDNReceipt automatically if AsyncMDNInfoDir is specified.
Note: MDNReceipt must be populated prior to calling VerifyReceipt.
AS3Sender.MDNTo Property
The system to which an MDN should be directed.
Syntax
getMDNTo(): string; setMDNTo(MDNTo: string): void;
Default Value
""
Remarks
If this property is set, a Disposition-Notification-To header will be added to the request, and an MDN will be requested. You should specify a valid FTP URL for the request, e.g., "ftp://123.0.0.1".
By default, the class will request a PKCS#7 signature signed over SHA-1. You may set MDNOptions to customize this.
AS3Sender.MessageId Property
The Id of the message.
Syntax
getMessageId(): string; setMessageId(messageId: string): void;
Default Value
""
Remarks
The Id format is as in RFC 2822: id-left@id-right .
A unique Id will automatically be generated on startup. Sending a message will reset id-left if the MessageId has been used in the previous message.
If you set MessageId to a string of the form "@(id-right)" a unique id-left will be generated. If you set MessageId to an empty string, a new MessageId will be generated with the same id-right.
After an MDNReceipt is returned or set, MessageId will contain the Original-Message-ID found in the MDN Receipt.
This property is not available at design time.
AS3Sender.OriginalContentMIC Property
The Message Integrity Check(s) (one-way hash) of the outgoing message.
Syntax
getOriginalContentMIC(): string; setOriginalContentMIC(originalContentMIC: string): void;
Default Value
""
Remarks
A MIC will be calculated over the outgoing message using the same algorithm in the SignatureAlgorithm configuration used to sign the message. The property will be set when Post (in AS3, Send) is invoked, and the MIC will automatically be checked against the Original-Content-MIC in the MDN for synchronous MDNs.
The format is in RFC 3335, i.e. "w7AguNJEmhF/qIjJw6LnnA==, md5", with a newline at the end.
If you are requesting an asynchronous MDN, you must save this value externally so that it can be loaded when the MDN is received (you may also use AsyncMDNInfoDir).
AS3Sender.Passive Property
This controls whether or not to direct the server into a passive mode. It is recommended if behind a firewall.
Syntax
isPassive(): boolean; setPassive(passive: boolean): void;
Default Value
TRUE
Remarks
This property controls whether or not to direct the server into a passive mode. Many firewalls will not allow the FTP server to open a connection from outside to the higher ports where the FTP client class expects them to be. If Passive is set to TRUE, the class will use the PASV command instead of the PORT command and thus will direct the server into a passive mode: connections are initiated only by the client.
AS3Sender.Password Property
This is the password used to log in.
Syntax
getPassword(): string; setPassword(password: string): void;
Default Value
""
Remarks
This property contains the password used to log in. It must be set before the class connects to the FTP server.
AS3Sender.ReceiptSignerCert Property
The public key certificate for the MDN receipt signature.
Syntax
getReceiptSignerCert(): Certificate; setReceiptSignerCert(receiptSignerCert: Certificate): void;
Default Value
Remarks
Ordinarily, if your trading partner uses the same certificate for both signing and encryption, the certificate specified in RecipientCert is used for both encryption and verifying the receipt signature.
If your trading partner uses different certificates for signing and encryption, you must set this property to the public key for you partner's signing certificate before invoking Post.
After invoking Post or VerifyReceipt, this will contain the certificate used to sign the receipt, if the receipt is signed.
If set, this property should be a public key instance of Certificate.
AS3Sender.RecipientCerts Property
The public key certificates of the recipients for this message.
Syntax
getRecipientCerts(): CertificateList; setRecipientCerts(recipientCerts: CertificateList): void;
Default Value
Remarks
The encryption certificates of the recipients. If this property is specified, the message content will be encrypted using the algorithm given by EncryptingAlgorithm.
This property will also be used to verify signed receipts if ReceiptSignerCert is not specified. In this case, it will use the first certificate found in the collection, if one exists. If your trading partner uses different certificates for signing and encryption, you should set RecipientCerts to the encryption certificate(s) and ReceiptSignerCert to the signing certificate.
If the class is unable to verify a signature make sure RecipientCerts are set appropriately.
If set, this property should could contain public key instances of Certificate.
This property is not available at design time.
AS3Sender.RemoteHost Property
This is the domain name or IP address of the FTP server.
Syntax
getRemoteHost(): string; setRemoteHost(remoteHost: string): void;
Default Value
""
Remarks
This property specifies the IP address (IP number in dotted internet format) or the domain name of the FTP server. It is set before a connection is attempted and cannot be changed once a connection is in progress.
If this property is set to a domain name, a DNS request is initiated and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.
If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.
AS3Sender.RemotePort Property
This is the port for the FTP service (default is 21).
Syntax
getRemotePort(): number; setRemotePort(remotePort: number): void;
Default Value
21
Remarks
This property contains the port for the FTP service, which defaults to 21 if not set. A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.
For an implicit Secure Sockets Layer (SSL), use port 990 (please see the SSLStartMode property for more information).
This property is not available at design time.
AS3Sender.SignatureAlgorithm Property
Signature algorithm to be used in outgoing messages.
Syntax
getSignatureAlgorithm(): string; setSignatureAlgorithm(signatureAlgorithm: string): void;
Default Value
"sha-256"
Remarks
Signature Algorithm can be set to indicate the preferred signing algorithm. Possible values are:
- sha1
- md5
- sha-256 (or sha256) (default)
- sha-384 (or sha384)
- sha-512 (or sha512)
- sha-224 (or sha224)
The default value is "sha-256". When this property is set the MDNOptions property is automatically updated to request the MDN receipt be signed with the same algorithm.
AS3Sender.SigningCert Property
Contains the certificate to use when signing messages.
Syntax
getSigningCert(): Certificate; setSigningCert(signingCert: Certificate): void;
Default Value
Remarks
This is your signing certificate. If this property is specified, the message content will be signed using the algorithm given by SignatureAlgorithm.
If set, this property should be a private key instance of Certificate.
AS3Sender.SSLAcceptServerCert Property
Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.
Syntax
getSSLAcceptServerCert(): Certificate; setSSLAcceptServerCert(SSLAcceptServerCert: Certificate): void;
Default Value
Remarks
If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.
You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.
Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.
AS3Sender.SSLCert Property
The certificate to be used during SSL negotiation.
Syntax
getSSLCert(): Certificate; setSSLCert(SSLCert: Certificate): void;
Default Value
Remarks
The digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the field to the encoded certificate. To select a certificate, use the store and subject fields.
AS3Sender.SSLProvider Property
This specifies the SSL/TLS implementation to use.
Syntax
getSSLProvider(): As3senderSSLProviders; setSSLProvider(SSLProvider: As3senderSSLProviders): void;
enum As3senderSSLProviders { sslpAutomatic, sslpPlatform, sslpInternal }
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.
When Automatic is selected the platform implementation will be used by default in all cases in the JavaScript edition.
Note: The Internal provider is not support at this time.
AS3Sender.SSLServerCert Property
The server certificate for the last established connection.
Syntax
getSSLServerCert(): Certificate;
Default Value
Remarks
SSLServerCert contains the server certificate for the last established connection.
SSLServerCert is reset every time a new connection is attempted.
This property is read-only.
AS3Sender.SSLStartMode Property
Determines how the class starts the SSL negotiation. By default, SSL will not be used.
Syntax
getSSLStartMode(): As3senderSSLStartModes; setSSLStartMode(SSLStartMode: As3senderSSLStartModes): void;
enum As3senderSSLStartModes { sslAutomatic, sslImplicit, sslExplicit, sslNone }
Default Value
3
Remarks
The SSLStartMode property may have one of the following values:
0 (sslAutomatic - default) | If the remote port is set to the standard plaintext port of the protocol (where applicable), the class will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit). |
1 (sslImplicit) | The SSL negotiation will start immediately after the connection is established. |
2 (sslExplicit) | The class will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS. |
3 (sslNone) | No SSL negotiation, no SSL security. All communication will be in plaintext mode. |
AS3Sender.Subject Property
The subject of the message.
Syntax
getSubject(): string; setSubject(subject: string): void;
Default Value
""
Remarks
The optional human-readable subject of the message. Some AS2 partners will use this field to send additional information about the transmission at the transport layer.
AS3Sender.Timeout Property
A timeout for the class.
Syntax
getTimeout(): number; setTimeout(timeout: number): void;
Default Value
60
Remarks
If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.
If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.
The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.
If Timeout expires, and the operation is not yet complete, the class .
Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
AS3Sender.User Property
This property contains the user identifier to use to log in.
Syntax
getUser(): string; setUser(user: string): void;
Default Value
""
Remarks
This property contains the user identifier to be used when logging in. It must be set before the class connects to the FTP server.
AS3Sender.abort Method
The method aborts the current upload or download.
Syntax
async as3sender.abort(): Promise<void>
Remarks
This method sends an ABOR command to the FTP server. It is used to interrupt file uploads and downloads.
AS3Sender.changeRemotePath Method
This method changes the current path on the FTP server.
Syntax
async as3sender.changeRemotePath(remotePath : string): Promise<void>
Remarks
This method changes the current path on the FTP server to the specified RemotePath. When called, the class will issue a command to the server to change the directory. The RemotePath parameter may hold an absolute or relative path.
Absolute Paths
If the path begins with a /, it is considered an absolute path and must specify the entire path from the root of the server. For instance:
component.ChangeRemotePath("/home/testuser/myfolder");
Relative Paths
If the path does not begin with a /, it is considered a relative path and is resolved in relation to the current directory. For instance, a value of myfolder will indicate a subfolder of the current directory. The special value .. refers to the parent directory of the current path. For instance:
//Change to the 'myfolder' sub-directory
component.ChangeRemotePath("myfolder");
//Navigate up two levels and then into the 'another/folder' path.
component.ChangeRemotePath("../../another/folder");
AS3Sender.config Method
Sets or retrieves a configuration setting.
Syntax
async as3sender.config(configurationString : string): Promise<string>
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
AS3Sender.deleteFile Method
This method removes a file specified by FileName from an FTP server.
Syntax
async as3sender.deleteFile(fileName : string): Promise<void>
Remarks
This method is used to remove a file specified by FileName from an FTP server. The remote file or directory specified by FileName is deleted. FileName is either an absolute path on the server, or a path relative to remote path set by ChangeRemotePath. If no FTP session is in place, one is automatically created by first calling the Logon method.

async as3sender.getFileTime(fileName : string): Promise<void>
Remarks
Gets the last modification time of the file specified by FileName and RemotePath on the FTP server.
AS3Sender.listDirectory Method
List the current directory on an FTP server.
Syntax
async as3sender.listDirectory(filesToList : string): Promise<void>
Remarks
A listing is requested for the directory or file mask specified in FilesToList. This can be an absolute path on the server, a path relative to RemotePath, or a file mask. The file listing is received through the DirList event.
Similar to ListDirectoryLong, except only file names are returned. If no FTP session is in place, one is automatically created by first calling the Logon method.
AS3Sender.listDirectoryLong Method
List the current directory on an FTP server.
Syntax
async as3sender.listDirectoryLong(filesToList : string): Promise<void>
Remarks
A listing is requested for the directory or file mask specified in FilesToList. This can be an absolute path on the server, a path relative to RemotePath, or a file mask. The file listing is received through the DirList event. Extended file information is returned.
If no FTP session is in place, one is automatically created by first calling the Logon method.
AS3Sender.logoff Method
This method is used to log off from the FTP server by posting a QUIT command.
Syntax
async as3sender.logoff(): Promise<void>
Remarks
This method is used to log off from the FTP server by posting a QUIT command. If that fails, the connection is terminated by the local host.
AS3Sender.logon Method
Logon to the FTP RemoteHost using the current User and Password .
Syntax
async as3sender.logon(): Promise<void>
Remarks
Logon to the FTP server using the current User and Password. If an SSL (TLS) connection is required, you should first set SSLStartMode.
Example (Logging On)
FTPControl.RemoteHost = "ftpserver"
FTPControl.User = "username"
FTPControl.Password = "password"
FTPControl.Logon()
AS3Sender.readReceipt Method
Reads and parses (but does not verify) an MDN receipt.
Syntax
async as3sender.readReceipt(filename : string): Promise<void>
Remarks
ReadReceipt will retrieve the file specified by Filename from the FTP server, and attempt to parse it as an MDN receipt. If the file is a valid MDN receipt, the class will determine the originator of the receipt and the MessageId of the original message. The originator of the receipt will be stored in AS3To, the intended recipient (presumably your system) will be stored in AS3From, and the original message Id will be stored in MessageId.
Pass in an empty string to skip the FTP transfer, and process the receipt specified by the MDNReceipt property instead.
You should then look up the original message and set OriginalContentMIC to the value of OriginalContentMIC originally computed when the message was sent (you will need to save this information externally). You should also set RecipientCert based on the value of AS3To if necessary. Also, set MDNOptions to the value used when making the original request.
Finally, VerifyReceipt should be used to verify the receipt.
AS3Sender.reset Method
Resets the state of the control.
Syntax
async as3sender.reset(): Promise<void>
Remarks
Reset resets the state of the class. All properties will be set to their default values.
AS3Sender.send Method
Prepares and sends the AS3 message.
Syntax
async as3sender.send(filename : string): Promise<void>
Remarks
Invoking Send will prepare and send the AS3 message. It will be signed if SigningCert is set, encrypted if RecipientCert is set, and compressed if CompressionFormat is set. A receipt will be requested if MDNTo is set.
Prior to sending, you may Logon to the FTP server and navigate to the desired RemotePath. If you have not created an FTP connection already then Send will attempt to establish one.
Filename should contain the name of the file that will be written on the AS3/FTP server. You may leave Filename blank to allow the class to determine an appropriate name.
AS3Sender.sendFTPCommand Method
Sends the exact command directly to the server.
Syntax
async as3sender.sendFTPCommand(command : string): Promise<void>
Remarks
This method sends the command specified by Command to the server exactly as it is provided. Use this method to send additional or custom commands directly to the server.
After calling this method check the FTPLastReply property and/or monitor the PITrail event to obtain the server's response.
AS3Sender.verifyReceipt Method
Verifies an MDN receipt.
Syntax
async as3sender.verifyReceipt(): Promise<void>
Remarks
VerifyReceipt verifies the receipt in MDNReceipt against the values of OriginalContentMIC and MessageId and the preferences specified in MDNOptions. The method operates similarly to Post: After the method finishes, the MDNReceipt, ReceiptSigningProtocol, and ReceiptSignerCert properties will be populated with the appropriate values.
The method operates synchronously, and will throw an exception if any errors or warnings occur. Errors might include a failure to decrypt or authenticate the receipt, the absence of an MDN when one was requested, TCP/IP errors, or any errors reported by the server in the MDN. Warnings might include the return of an unsigned receipt when a signed receipt was requested, or other warnings reported by the server in the MDN.
If an exception is thrown the error code will correspond to the severity of the warning or error, allowing client software to determine whether or not to accept the reply. If multiple errors occur, the exception will return a special error code, and the error message will contain a line for each error's code and description; i.e. "423: Failed to authenticate sender". If the error(s) is/are not fatal processing will not be interrupted, and the relevant properties will be populated as normal.
You should first invoke ReadReceipt when it is not known which message the receipt is in response to. This will allow you to determine the original MessageId and originator of the receipt before trying to verify it.

Config Settings (class ipworksedi.as3sender)
The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.AS3Sender Config Settings | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
CalculateProcessingPercentDone: Whether to show the progress of file processing.When set to True the class will display the progress of file processing (encrypting and signing) through the StartTransfer, Transfer, and EndTransfer events. The default value is False. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
LogFilename:
The base name of the log file.If set, this will be used as for the filename of the log file.
Note that only the base name should be specified as the component will append the appropriate file extension. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
LogonAfterProcessing: Whether to prepare the file before connecting to the FTP server.This setting controls whether the class connects to the FTP server before or after processing the file to be sent. When set to True the class will perform any signing and encrypting operations to prepare the file before connecting to the FTP server. When set to False the class will connect and then prepare the file immediately before upload. The default value is False. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FTP Config Settings | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ActiveModeIP:
Allows the specification of the IP address that the server will connect to for active mode connections.The ActiveModeIP configuration setting can be used to specify the IP address that the server will connect to when
using an active mode configuration (Passive = False). When this configuration setting is set, the port number where the component
listens for active mode connections will still be managed by the component. The PortRange also can
be used to ensure that the correct port is used by the client.
Note: This configuration setting will be ignored if ActiveModePORTAddress is also specified. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ActiveModePORTAddress:
Allows the specification of the PORT address value for active mode connections.When using an active mode configuration (Passive = False) with a firewall, it may be necessary to specify the actual PORT value to be sent to the server. ActiveModePORTAddress takes the protocol-level parameter in the form "a,b,c,d,e,f" where "a,b,c,d" is the external IP address separated by commas, and e and f represent, respectively, the high-byte (divide by 256) and the low-byte (mod 256) values of the external port where the FTP client is listening.
This configuration setting must be used in conjunction with PortRange to ensure that the correct port is used by the client. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
AppendToLocalFile: Append downloaded files to a local file.If set to True, the downloaded files will be appended to the file specified in LocalFile. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ApplyFileMaskLocally: Whether to filter the directory listing locally or on the server.If set to true any filemask provided to RemoteFile will be applied locally, after the server has returned the results. When set to false (default), the value in RemoteFile will be sent to the server as part of the relevant listing command. Because using filemasks with list commands is not standardized, some servers do not support them and will return an error. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
AutoSelectDataIP:
Automatically select the data connection IP.This setting controls the selection logic of the data connection. By default, this value is True and the
class will attempt to determine the best IP for the data connection based on the returned value from the server.
It is recommended to leave this value set to True unless there is a reason to disable it.
In many cases, FTP servers are not configured to return a valid public IP in the PASV response. When Secure Sockets Layer/Transport Layer Security (SSL/TLS) is used any network address translation (NAT) done by the firewall cannot occur. The result is the client may receive an IP that is not accessible. This setting is designed to allow the connection to succeed in as many cases as possible. When the IP for the data connection is received from the server, the class will inspect the value. If the received value is not within the known private IP ranges, the class will use it, assuming it is a valid public IP. If the received value is a private IP, the class will instead assume the data connection should be established to the same IP as the command connection (true in almost all cases). When this setting is False, the class will not perform any checks on the received value. When set to False, UseRemoteHostAddressForPassive is applicable. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
CalculatePercentDone: Enables or Disables calculating the percent complete for downloads.When set to true (default), the class sends an FTP SIZE command to retrieve the file size before beginning a download. When downloading a large quantity of small files, performance may be increased by disabling this feature. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
CheckTotalEntry: Whether to ignore directory listing total lines.Some servers will include "total" information when returning a directory listing that contains non-entry data. When CheckTotalEntry is set to True (default), the component will ignore lines beginning with "total" to account for this. In some cases, it may be desirable to include these lines in the resulting DirList data; this can be done by setting this configuration setting to False. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DILinger:
When set to True, DI connections are terminated gracefully.
This property controls how the DI connection is closed. The default is True.
In the case that DILinger is True (default), follow two scenarios to determine how long the connection will linger. In the first scenario, if DILingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires. In the second scenario, DILingerTime is a positive value, the system will attempt to send pending data until the specified DILingerTime is reached. If this attempt fails, then the system will reset the connection. The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes). Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DILingerTime: Time in seconds to have the DI connection linger. LingerTime is the time, in seconds, to let the socket connection linger. This value is 0 by default, which means it will use the default IP timeout. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FileTimeFormat:
The format of file time reported by the server.The default value is "M/d/yyyy hh:mm:ss tt". When set, the class will format the time returned by the server when calling the QueryFileTime method.
To disable all formatting, set this to empty string.
Note: This setting applies only when calling QueryFileTime. It does not apply to the FileTime parameter of the DirList event. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
IgnoreEntries: Directory entry data to ignore.Sometimes the FTP server will return data in a directory listing that is not entry data and can be ignored. The IgnoreEntries configuration setting takes a comma-separated list of entries to ignore. Only the beginning of the entries need to be specified and correct case is not required. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MaskSensitive: Masks passwords in logs.The default value is False. When set to True, the class will mask passwords that otherwise would appear in its logs. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ModeZCompressionLevel:
Used to specify the level of compression used.The default value is 7. Valid values range from 0 to 9. A higher value indicates that a higher compression level is being used. This is valid only when UseModeZ is set to True.
Note: When this setting is specified the class immediately performs an action. Use the ConfigAsync method in order to avoid blocking execution. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
PortRange:
Allows the specification of a port range where the class listens for active mode connections.When set to use active mode (Passive = False), the class uses any available port
to listen to incoming connections from the server. You can override this behavior by setting
PortRange to a value containing the range of ports the class will be
listening to.
The range is provided as start-end, for instance: "1024-" stands for anything higher than 1024, "1024-2048" stands for ports between 1024 and 2048 inclusive, "4000-4010, 50000-50010" stands for ports between 4000 and 4010 or between 50000 and 50010. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
PreserveFileTime: Attempts to preserve timestamps when transferring files.When set to True, the class will try to preserve timestamps when transferring files. The MDTM command is used when downloading, and the MFTM command is used when uploading. The server must support these commands for this to work and is False by default. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
RealTimeUpload: Enables real time uploading.When this value is set to True, the class will upload the data in the file specified by LocalFile and continue monitoring LocalFile for additional data to upload until no new data is found for RealTimeUploadAgeLimit seconds. This allows you to start uploading a file immediately after the file is created and continue uploading as data is written to the file. The default value is False. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
RealTimeUploadAgeLimit: The age limit in seconds when using RealTimeUpload.This value is only applicable when RealTimeUpload is set to "True". This specifies the number of seconds for which the class will monitor LocalFile for new data to upload. If this limit is reached and no new data are found in LocalFile the upload will complete. The default value is "1". | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ReusePISSLSessionInDI: Whether the PI SSL session will be reused for the DI connection.When set to True (default), the class will reuse the PI SSL session when creating the DI connection. When set to False, the class will create a separate SSL session for the DI connection. The default value is True. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ReuseSSLSessionInDI: Whether the SSL session will be reused for the DI connection.When set to True (default), the class will ask the server to reuse the existing DI Secure Sockets Layer (SSL) session. When set to False, a new SSL session will always be created for the DI connection. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseClearChannel: Allows for the Clear Command Channel (CCC) command.When this is set, the class will send the CCC command to the server requesting a clear (unprotected) command channel. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseClearDataChannel: Allows for the PROT C command.When this is set, the class will use a clear (unprotected) data channel by sending the PROT C command to the server. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseEPSV: Allows extended passive mode.When this is set, the extended passive mode will be used. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseMLSD:
Uses listings for machine processing.When this is set to True, the class will list files in the directory using the MLSD command. This command is an extension
to the protocol that defines a more standardized and reliable directory listing format.
Not all servers support this command. The default value is False.
When set to True, set RemoteFile to the filemask and call either ListDirectory or ListDirectoryLong. There is no difference between the two methods when this setting is enabled. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseMLST:
Uses single file listing for machine processing.This setting is similar to UseMLSD except that it is valid only for a single file.
When this is set to True, the class will list the file or folder specified by RemoteFile. If RemoteFile
is not set, a listing for the current directory will be returned. This command is an extension
to the protocol, which defines a more standardized and reliable directory listing format, but does so only for a single file or folder.
Not all servers support this command. The default value is False.
When set to True, set RemoteFile to the file or folder you wish to get information about and call either ListDirectory or ListDirectoryLong. There is no difference between the two methods when this setting is enabled. When both UseMLSD and UseMLST are set, UseMLSD takes precedence. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseModeZ:
Allows compression to be used when transferring data.The default value is False. When set to True, the class will issue the MODE Z command to the FTP server.
This will enable deflate compression so that all data transferred are first compressed either by the server (when downloading) or by the class (when uploading). Note: Not all servers support this feature.
Note: When this setting is specified the class immediately performs an action. Use the ConfigAsync method in order to avoid blocking execution. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseOldAUTHSSL:
Allows use of the 'AUTH SSL' command instead of 'AUTH TLS'.By default, the class uses the standard AUTH TLS command to initiate
the SSL handshake with the server. This configuration setting is included
for optional support of older servers that support only the AUTH SSL
command.
Note: Using AUTH SSL instead of AUTH TLS is strongly discouraged because of potential security vulnerabilities. If you must use this configuration setting, please do so very carefully. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseProtWhenImplicit: Sends the PROT P command to the server.When SSLStartMode is set to sslImplicit, setting this to True will instruct the class to send the PROT P command to the server. This explicitly tells the server that the data channel will be protected. The default value is True. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseRemoteHostAddressForPassive:
Instructs the class to use the address specified by RemoteHost when establishing a data connection.When this setting is True, the class will use the address specified by RemoteHost when establishing a
data connection for directory listings and file transfers. This setting is applicable only when AutoSelectDataIP is set to False.
When this setting is False (default) and AutoSelectDataIP is also False, the class will use the IP address returned by the server when establishing a data connection. This setting is not applicable when Passive is set to False (Active mode). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
VirtualHostName: Sends the HOST command to the server.Defined in RFC 7151, the HOST command allows user-FTP processes to specify which virtual host to connect to for a server-FTP process that is handling requests for multiple virtual hosts on a single IP address. When this configuration setting is set, the HOST command is sent to the server before authenticating. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
TCPClient Config Settings | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ConnectionTimeout: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FirewallAutoDetect: Tells the class whether or not to automatically detect and use firewall system settings, if available.This configuration setting is provided for use by classs that do not directly expose Firewall properties. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FirewallHost:
Name or IP address of firewall (optional).If a FirewallHost is given, requested connections will be authenticated through the specified firewall
when connecting.
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned. Note: This setting is provided for use by classs that do not directly expose Firewall properties. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FirewallPassword:
Password to be used if authentication is to be used when connecting through the firewall.If FirewallHost is specified, the FirewallUser and FirewallPassword settings
are used to connect and authenticate to the given firewall. If the authentication fails, the class .
Note: This setting is provided for use by classs that do not directly expose Firewall properties. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FirewallPort:
The TCP port for the FirewallHost;.The FirewallPort is set automatically when FirewallType is set to a valid value.
Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FirewallType:
Determines the type of firewall to connect through.The appropriate values are as follows:
Note: This setting is provided for use by classs that do not directly expose Firewall properties. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
FirewallUser:
A user name if authentication is to be used connecting through a firewall.If the FirewallHost is specified, the FirewallUser and FirewallPassword
settings are used to connect and authenticate to the Firewall. If the authentication fails, the class .
Note: This setting is provided for use by classs that do not directly expose Firewall properties. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
KeepAliveInterval:
The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, TCPKeepAlive will automatically be set to True.
A TCP keep-alive packet will be sent after a period of inactivity as
defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet
will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds.
This system default if this value is not specified here is 1 second.
Note: This value is not applicable in macOS. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Linger:
When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires. In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection. The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes). Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
LingerTime: Time in seconds to have the connection linger. LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
LocalHost:
The name of the local host through which connections are initiated or accepted.
The LocalHost setting contains the name of the local host
as obtained by the gethostname() system call, or if the
user has assigned an IP address, the value of that address.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface). |

LocalPort:
The port in the local host where the class binds.
This must be set before a connection is
attempted. It instructs the class to bind to a specific
port (or communication endpoint) in the local machine.
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established. LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MaxLineLength:
The maximum amount of data to accumulate when no EOL is found.MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL
string.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset. If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset. The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MaxTransferRate: The transfer rate limit in bytes per second.This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ProxyExceptionsList:
A semicolon separated list of hosts and IPs to bypass when using a proxy.This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use.

Note: This value is not applicable in Java. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
TcpNoDelay:
Whether or not to delay when sending packets.
When true, the socket will send all data that is ready to send at once. When
false, the socket will send smaller buffered packets of data at small intervals.
This is known as the Nagle algorithm.
By default, this config is set to false. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseIPv6:
Whether to use IPv6.When set to 0 (default), the class will use IPv4 exclusively.
